I really recommend a trip to the Morro Dois Irmãos, which translates as the Twin Brothers Hill, when you need to cool off and fancy a half day's excursion. You can hike up the two cliff formations, which can be seen from far and wide – adventure guaranteed! Getting up to the top, passing through the peaceful favela, is an experience in itself. You can take a taxi to the Sheraton Hotel, from where you can take a motorbike taxi to the sports ground. This is where the hike begins. It follows easy paths through beautiful Atlantic rainforests on the coast, where you may be lucky enough to spot some common marmosets. Those reaching the summit are rewarded with a sensational view. It is one of the few places where you can admire the Sugarloaf Mountain, statue of Christ and the beaches all at once. And you don't have to share the view with hundreds of tourists, either.
